SPECIFICATION vforming part of Letters Patent No. 617,253, dated January3, 1899.

Application tiled March 4, 1898. Serial No. 672,577. (No model.) I

,To @ZZ 'wl/,om t may concern:

Beit known that we, FRANK B. MANVILLE and CHARLES SNVEEKS, citizens ofthe United ject is to produce a machine which will automatically severwire into lengths, then bend one end of each length to form a loop, thentwist the lapping portions to leave an eye, and finally deposit thefinished ties in a receptacle, means being also provided for giving asignal when a predetermined number of ties have been so deposited, andprovisions being also made for adjusting the feed ofthe wire to produceties of the desired length.

Further objects of our invention are to produce a machine of this typewhich is simple in construction, in View of the several manipulationsandtransfers of the lengths of wire, and which machine is capable ofproducing the finished ties at a high rate of speed.

To these ends our invention consists in the construction and combinationof parts, substantially as hereinafter described and claimed.

Figs. 30 and 31 represent enlarged detail views, partly insection, of the means for signaling the finishing of a particular numberof the baleties, the bearing for the worm-shaft being omitted from Fig.30.

Similar reference characters indicate the same parts throughout theseveral views.

The bed-plate of the machine is indicated roo at l, supported by legs 2and having suitable bearings for the main shaft 3 and counter'- shaft a,the former having a pulley 5 for a driving-belt (not shown) and thelatter having the cams, hereinafter described, secured thereto. Atoneend of the shaft 4 is a gear S,- meshing with and driven by a pinion 9on the main shaft. fit the other end of the counter-shaft or cam-shaft@t is a gear 11, (see Figs. l, 3,1-, and 5,) which meshes with a gear 12on a short shaft 13, mounted in a bracket 15, (see Fig. 5,) that issuitably secured to the frame of the machine. Both of the shafts 3 andet also have their bearings in this bracket 15 and also in anotherbracket 1G, (see Figs. l and 2,) secured to the frame or bed of themachine, at the front side thereof, as viewed in Fig. 2.

Secured to the end of the shaft 13 and adjacent to the gear 12 is a disk17, having a dovetail groove 1Q formed diametrically across its face, inwhich groove a block 2O (see dotted lines in Fig. a) is fitted andadapted to be moved radially by means of a threaded rod 21, which passesthrough a similarlythreaded hole in said block in a well-known manner.Near the outer end of the rod 2l are fixed collars 22, between which isa block 23, secured in the groove 19. The end of the rod has a squaredsocket, whereby a wrench or key is employed to rotate the rod and adjustthe block 20 toward and from the center of the disk 17. The said block2O carries a wrist-pin 2i, which enters a slot 2G in a lever 27, thelatter being pivoted to the frame, as at 2S. As will now be understood,the throw or extent of movement of the lever 27 may be adjusted by meansof the threaded rod 21, and since this lever operates the feed, aspresently described, the adjustment of the block 2O and its wrist-pin2st by means of said rod 21 effects the desired adjustment of the feedof the wire.

The feed-disks 30, between the grooved peripheries of which the wire isgripped and by the rotation of which the wire is drawn from a suitablecoil or other source of supply, (not shown,) are represented in Figs. 1,2, and 3, and their operatingmechanism is shown more in detail in Figs.G, 7, and 8. A standard 3l, rising from the bed-plate l and forming partof the frame of the machine, is provided with two offsets 32, (see Figs.3 and 6,) which are provided with dovetail grooves in line with eachother to form ways for a slide 33, the upper and lower edges of whichare toothed to form a rack. rl'his slide-rack is connected with theupper end of the lever 27 by a pitman or connecting-rod 34, wherebymovements of said lever reciprocate the sliderack to a greater or lessextent, according to the adjustment of the wrist-pin above described.

ln the standard 3l are bearings for the sleeves or tubular shafts 35,one end of each of said shafts having secured thereto or integraltherewith a pinion 36, which meshes ariete with one of the compoundpinions `17, presently described, and the other end having aratchet-toothed disk 37. (See Figs. G and 7.) Each sleeve or shaftreceives or forms a bearing for a shaft 3S, on the outer end oi which ismounted one of the feeddisks 30, having a pawl 39 in engagement with theratchet 37. The hubs of the feed-disks are somewhat extended to formbearing-surfaces 40 for friction-pads 41, of any suitable material, saidpads being held in position by a yoke or strap l2, (see Fig. 8,) theupper ends of which are threaded and passed through a cap 43 and areprovided with nuts il, by means of which the two friction-pads maybeadjusted to bear with more or less pressure on the surfaces 40.

As shown in Fig. 0, one side of the stand ard 31 is provided withthreaded sockets l5. These are to receive studs 4G, (see Fig. 3,) onwhich are freely mounted compound pinions 4,7, the larger of which meshwith the pinions 3G and the smaller of which mesh with the two racksformed on the reciprocating slide It will new be understood that thereciprocations of the slide-rack canse the ratchets 37 to have areciprocating rotary motion through the medium of the tubular shafts 35and the pinions 3G and idlerpinions i7, and that when this motion is inone direction the disks will be caused to rotate in the direction of thearrows thereon in Figs. 3 and 7, owing to the enga-gement of the pawlswith the ratchets, and that on the return movement of the reciprocatingparts the ratchets move freely under the pawls, while the disks areprevented from retrograding by the friction-pad mechanism abovedescribed. rlhe diameters of the feed-disks are such and the compoundpinions `17 are so proportioned for multiplying speed that with asomewhat limited throw of the lever 27 we are enabled to obtain awire-feed of any desired length, according to the dimensions and thethrow adjustment of the lever.

The wire is passed directly between the feed-*disks and is preferablydrawn through a wire-straightening mechanism, (indicated at 48 in Fig. 2in a conventional manner.) This mechanism maybe of any preferred form,and we do not illustrate itin detail, it being suliicient for thepurposes of this specification to state that it is mounted on a standard50 and is of a type that is rotated about the wire as it is drawn along'by means of a power-driven belt 49.

A fixed guide 51 (see Figs. 2, 9, and lO) is provided with a tapered endto enter the space between the feed-disks at the discharge side ot'their contacting points and has its internal longitudinal bore orpassage of a size to receive the wire as it leaves the feed-disks. Thisguide is secured in an ear 52, projecting from a plate 53, by means of aset-screw 54:,

and said plate is adj ustably secured on a portion of the standard 31 bymeans of a screw IOO IIO

` ceivers.

cir/,25s a passing through a slot 5G in said plate. The rear end of theguide is preferably somewhat rounded, and with this a cutter 57cooperates to sever the wire after each feed movement has ceased. Thecutter is adjustably secured to a slide 58 by means of a screw 59passing through a slot GO in the cutter shank, and said slide is fittedto a groove or way formed in the plate 53 at a right angle to the guide5l. A spring 6i is confined between a portion of the plate 58 and anangular offset 62 of the slide 58 and tends to hold the slide and cutterin inoperative positions and to return them after the wire has beensevered, aswill now be described.

A lug or shoulder G8, rising from the cutter-slide, is operated againstby one end of a lever 64, (see Fig. 1,) which passes through an opening65 in the standard 31 (see Fig. 6) and is fulcrumed in said opening by apin, as indicated by the dotted circle GG in Fig. l. The other end ofthe lever 64 carries a pin or roll 67, which is operated against by acam G8 on the end of a drum 69, mounted on shaft 4. This cam operatesquickly and at a time after the feed or advance of the wire has ceased.

Referring to Fig. 3, it will be seen that at some distance from the mainframe of the machine is a leg or standard 70. rlhis, in connection withparts of the main frame, supports the parts which temporarily hold thesevered blanks or lengths of wire and also carries the outer bearing forthe shaft of the rotary carrier or transferrer, hereinafter described.

The upper end of the standard .70 is connected with a standard 7l,rising from the bed-plate l, by means of a rod 72, which supports thetemporary receiver or table for the blanks. Ne have illustrated but onestandard but it is to be understood that more may be employed and thatthe receiver or table may be of any length to accommodate the greatestlength of blanks desired. As shown in the drawings, the receiver is intwo sections to permit the ends of one set of arms of the tran ferrer topass between the sections, the other set of arms being beyond the end ofthe receiver, (see Fig. 8;) but when more sets of transferrer-arms areemployed there will be added standards 7 O and sections of re- The twosections of receivers illustrated are supported from the rod 72 by meansof hangers 78, (see Figs. l, 2, and 8,) and each section consists of abase portion or table 74:, to which is hinged, by means of suitableears, a cover 75, having a groove 7G in its lower face, (see Figs. 24,25, 26, and 27,) the two sections of covers being connected bya bridgeor strip 77, as shown in Figs. l, 2, and 3.

The groove 7 G is in line with the exit end of the orifice for the wirein the guide 5l and receives the wire before it is severed by the cutterand holds it while being cut off. ln order to release the blank from thegroove, so that it may be taken by the vlingers at the ends of the armsof the transferrcr, (not yet described,) it is necessary to raise thecover on its hinges. In Figs. 24E to 27 we illustrate a single arm 7 8,extending back of the hinged edge of the cover; but it is to beunderstood that in practice there may be a number of such arms 78, eachhaving means to depress it to raise the front edge of the cover, asshown in Figs. 26 and 27.

rlhe arm 78 is depressed at the proper time by means of an elbow-lever79, pivoted at 8O to one of the hangers 78 and having its longer orhorizontal arm extending over the arm 78. The upper arm of theelbow-lever is connected by a link 8l with another elbow-lever 82,pivoted at 83 to another hanger 7 9. The lever 82 is connected by a link84 with an arm 85 of a roclcshaft 8G, (see Figs. 24 and 26 in connectionwith Figs. 1, 2, and 3,) mounted in a bearing at the upper end of astandard 87, rising from the bed-plate of the machine. Another arm 88 ofthe rock-shaft is provided with a pin 89 and has attached to it one endof a spring 90, the other end of the spring being connected at 91 to thebed-plate of the machine. (See Figs. 24: and 26 in connection with Fig.3.) The parts are normally held in the positions shown in Figs. 3, 24,and 25 by the tension of spring 90, thus permitting the cover to remainclosed. To raise the arm 88 and through the connections described causethe elbow-lever 79 to depress the arm 78 and raise the cover, we provideayielding finger 92, pivoted to the slide at 93. (See Fig. 8.) rlhefinger carries a pin 9i on one side, and back of the linger a pin 95projects from the slide and acts as a backstop to prevent the fingerfrom moving in that direction. A spring 9G connects the pins 9i and 95and serves to normally hold the finger against the back-stop. During thebackward movem ent of the slide-rack 38 the spring 96 yields and permitsthe pivoted finger 92 to pass under the arm 88 without disturbing thelatter; but on the forward movement of the slide-rack the finger is heldupright by the back-stop 95, and consequently the upper end of thefinger slides along the under side of the arm 88 and lifts it, and thusthrough the connections described raises the cover 75. The cover 75 isheld in raised position all the time the finger 92 is passing along thestraight under side of the arm 88 toward the end of the latter, thusgiving the transferrer-arm 123, which is hereinafter described, time tocarry a wire blank out from under the cover '7 5.

It is to be borne in mind that the forward movement of the slide-rackjust described does not feed the wire, said feed taking place only whenthe rack is moving to the left from the position shown in Fig. 3.Therefore the cover 75 is lifted to release the wire after the feed hasceased and after the requisite length has been cut olf and just beforethe next feed movement of the disks.

As hereinbefore stated, there are two or morev sets of arms in themechanism. for tak- IOO IOS

ing the blanksl from the iemporz'iry receiver just described. 1n thedrawings there are tivo of such sets illustrated, the ends of the armsof one set passing betiveen the adjacent ends of tivo sections of thereceiver. During each feed of the Wire these arms are stationary and theivire is fed through openings in the ends of the arms which are at thattime in alinement with the guide 51 and with the groove of the temporaryreceiver. Ve will now describe the construction and operation ci' thismechanism which takes the blanks from said receiver and transfers themfirst to the twisting mechanism and then to the final receiver.

1n connection With Figs. 1, 2, and 3 reference is to be had to Figs. 10,20, 21, 22, 23, and 27. The shaft 07 of the rotary transferrer ismounted in suitable bearings 0S and 00, supported, respectively, by thestandards 70 and 71, and said bearings are vertically adjustable inorder to insure that the openings in the ends of the arms may be broughtinto exact alinement with the groove 7 0 of the temporary receiver. Themeans by Which this adjustment may be effected are illustrated in Fig.10, in which the bearing-sleeve 09 is shown as provided with t\vosockets to re ceive the ends of screws 101, tapped through suitableopenings in portions of the standard 71 and provided with set-nuts 102.The inner end of the shaft 07 extends through the bearing-sleeve .10 andhas secured thereto a disk 103, provided with four equidistant notches101, each of which has a radial side and a tangential side, (see Fig. 20in connec tion With Fig. 19,) and secured adjacent to or forming a partof the disk 103 is a collar or ila-nge 105, Which also has fonrequidistant notches, as at 100, these latter, however, hav ing sidesWhich are substantiallyparallel, but tlaringsomewhatat their months, asindicated by dotted lines in Fig. 20. A bolt 107 is adapted to enter anyone of the notches 106 to hold and lock the iiange 105, disk 103, andthe shaft 97 and its arms in proper position for the alinement of theopenings in the ends of said arms above mentioned and to be presentlydescribed in detail. This bolt 107 is mounted to slide in a horizontalgroove or Way formed in a block 10S, that is fixed to a portion of theframe of the machine, and the said boltis normally held in one of thenotches 100 by a spring 100, coiled abont a pin 110 in the side of theblock and having one end secured, as at 111, and the other end pressingagainst the outer side of a pin 112, projecting from the side of' thebolt.

Loosely pivoted on the end of the shaft 07 is a lever 113, having oneend formed as a cam-surface 11i, which is adapted to engage the innerside of the pin 112 of bolt 107 and force the bolt out of the notch inthe flange against the action of spring 100, and thus release thetransferrer. The other end of the lever 113 is provided With a pawl 115,which is kept in engagement with the periphery of the disk 103 by asuitable spring. (Not shown.) XVhen the lever 113 is moved onefourth ofa rotation to the right from the position shown in Fig. 20, the pawl 115enters the notch 101A at the right just as the cam 111 engages the pin112 of the bolt and causes the release of the transferrer, so that onthe return movement of the lever to the position shown in Fig. 20 thedisk 103 and the entire transferrer is given a one-fourth revolution.These oscillating movements of the lever are imparted by means of alever 110, pivoted at 117 (see Figs. 2 and 3) to a bracket on the underside of the bedplate and having at one end a roll 11S, riding on a cam110, carried by shaft t. A spring, as at 120, keeps the roll inengagement With said cam, and the other end of the lever 11G isconnected with the lever 113 by a link 121, adjustably ,jointed, as at122, in order to secure exactness in the throiv of the lever 113.

The means for intermittently rotating the transferrer having thus beenexplained, ive will noiv describe the construction of thc detailsthereof, referring particillarly to Figs. 21, 22, 23, 27, 2S, and 20 inconnection with Figs. 1, 2, and 3.

The shaft 07 is provided with a plurality of sets of arms, each setconsisting of four arms 123 equidistant from each other. As the sets ofarms are duplicates of each other, description of one set and of themeans for retaining the blanks in their openings and for dischargingthem therefrom will be sullicient for all. In the end of cach arm 123 isan open slot or recess 124, which is normally closed by a latch or hook125, formed on the outer end of a lever 120, pivoted to the arm at 127and having a pin 128 projecting from its other end. A spring is coiledabout the pivot-pin and has one end connected to the pin 128 and theother end connected to a stud 130, projecting from the arm 123. Thespring has a tendency to hold the lever in engagement with the stnd130,with the hook overlapping the recess 12a, so as to form a substantiallycircular opening for the Wire. On the side of each arm opposite that towhich the lever is pivoted is a stud 131, having a recess correspondingwith the recess 121 and provided with a conical entrance-mouth (seedotted lines in Fig. to guide the end of the Wire as it approaches thearm As each arm reaches its lowermost position the hook is opened topermit the wire to be dropped out by means of a stop or lug 132, (seeFigs. 2S and 20,) carried by an arm 133, adjustably supported in aslideway formed in a bracket 131x, carried by a suitable part IOO IIO

of the frame. This lug 132 is arranged in the path of movement of theend of the lever 120, so that when said lever 120 contacts with the lug132 it will first cause the hook to open the recess in the arm 123 torelease the Wire or baletie, and then pass by the lug, so that thespring 129 Will cause the hook to close the recess again.

.Before the operation of releasing the tie, as just described, takesplace the wire blank has had one end doubled and twisted while held bythe arms 123 in a stationary position half-way between the posit-ions ofreceiving and discharging, and We will non7 describe4 the mechanism forperforming this operation. Referring to Figs. 1, 2, and 11 to 18,inclusive, the shaft of the twister is indicated at 135, mounted in abearing formed in a block 136 on the bed-plate 1, the cap-piece of thebearing being indicated at 137. The rearend of said shaft is providedwith a pinion 138, which meshes with and is driven by a gear 139 on ashort shaft which is mounted in a bearing in a block 140 and hasasmallergear or pinion 141 at its other end. The pinion 141 meshes with and isdriven by a rack 142, fitted to slide in a suitable guide or Way (notshown) in the side face of the block 140 and having a stud provided witha roll 143, which enters a cam-groove 144 in the drum or cylinder 69 onshaft 4. Each rotation of the shaft 4 and its cam-cylinder imparts tothe slide-rack a complete forward-andback movement, and this through themultiplyinggearing 138, 139, and 146, above described, rotates the shaft135 several times in one direction (about three as now geared) and thenreturns the shaft. The cam-groove 144, however, is formed so as topermit a dwell in the movements of the shaft at the end of each seriesof rotations in one direction, for a purpose presently explained. Theother end of the shaft 135 is divided so as to form a recess 145 toreceive one end of the Wire blank cc as it is passed thereto by the armsof the transferrer at the end of the first quarter-revolution of saidtransferrer. The ends of the two arms 146 each side of the recess 145are provided with openings in line with each other to receive a pin 147,the inner end of which is beveled, as at 148 in Fig. 18, to prevent theend of said pin from catching on the wire when the pin is moved inward,and the outer end of said pin 147 is connected to a lever 149, pivotedto an ear 150 on the outer side of one of the arms 146. The lever 149 isprovided with a pin 151, on Which a spring 152 bears to hold the levernormally in the position shown by full lines in Fig. 11, with the pin147 withdrawn from across the recess 145.

TWO lugs 153 depend from the lower edges of the arms 146 and support apin 154, which in turn supports and guides the bending-iinger 155. Thisbending-finger is of peculiar construction, its outer portion or tip 156eX- tending upward in an inclined direction and then curving forward anddownward and having a groove 157 `formed in its upper edge, which groovecontinues over and under the end, as clearly shown by the full lines inFig. 11 and by dotted lines in Figs. 15, 16, and 17. The intermediateportion of the bending-finger is provided with a slot 158, `that iscurved in a direction substantially the .reverse of the curvature of thetip 156, and this slot receives and serves to guide the finger on thepin 154, so that when a wire has been lowered by the transferrer to theposition indicated by full lines in Fig. 12 and the 1ever 149 has beenoperated by the means presently described to move the pin 147 across therecess 145 and the finger 155 is then advanced by the means presentlydescribed the tip of the finger bends the Wire up and over the pin 147until the short endlies close to the portion of the Wire that is stilllying in the arms of the transferrer. (See Figs. 12, 15, and 16.) Toeffect these movements of the lever 149 and finger 155, We employ asleeve 159, movable on the shaft 135 and provided With an annular groove160, which receives the arms of a yoke 161, attached to a slide-bar 162.This slide-bar is itted to a groove in the base of the block 136 and hasits rear end provided With a roll 163, Which enters a cam-groove 164,(see dotted lines in Fig. 1,) formed in one side of a disk 165, carriedby shaft 4. The time of operation of this cam-groove is such as toadvance the sleeve 159 while the shaft 135 is stationary, as heretoforedescribed.

The sleeve 159 is provided with a projecting Wedge or incline 166 inline with the end of the lever 149 (see 'Figs 11, 13, and 14) and withtWo ears 167, (see Figs. 12, 13, and 14,) Which are provided With shortslots 168. The inner end of the finger is fitted between the ears 167and carries a pin 169, Which rides in said slots. By this constructionwhen the sleeve 159 begins its advance movement the incline 166 firstrides under the end of lever 149 and moves the latter and the pin 147from the position shown in full lines in Fig. 11 to the position shownby dotted lines in said figure, and then the inner ends of the slots 168come in contact with the pin 169 of the finger 155 and advance thelatter from the position shown by full lines in Fig. 12 to the positionshown by dotted lines in said figure and bending the Wire over the pin147.

Referring now to Figs. 1 and 2, it will be seen that the side of theblock 108 is formed as a -fixed jaw 170, with which a movablejaw 171coperates, the -latter being carried by a lever 172, pivoted to thebed-plate 1 at 173 and having its other end provided With aroll 174,which is acted upon by a cam 175 on the side of the disk 165, a spring176 being employed to keep the roll in engagement With the said cam. Thetiming of the operation of this cam 175 is such as to cause the jaw 171to move toward the jaw 170 and grip the doubled Wire at about the pointindicated at y in Fig. 16 just after the finger 155 has ceased tooperate. Immediately after this gripping action takes place the straightpor tion of the cam-groove 144 has left the roll 143 and the inclinedportion of said groove acts on the roll to move the rack 142 and,through the gearing before described, the

shaft 135 is rotated and the wire is twisted, as indicated in Fig. 17,leaving a loop or eye at the end of the finished tie.

In order to hold the shaft 135 in exact position, with the recess in avertical plane to permit the wire to be carried into said recess by thetransferrer and to permit the iinished tie to be carried down and out ofsaid recess by the transferrer at its next quarterrevolution, we affixto the shaft a colla-r 177, having a fiat side 178. A plate (see Figs. 1and 2) is secured at 011e end on the cap-piece 137 and has a slot toreceive a guidepin 180, rising from said cap-piece. The free end of theplate 170 is formed as a block 181, overhanging the end of the cap-pieceand resting on the collar 177. A flat spring 182 is secured at one end183 and bears at its other end on the plate 170. The collar 177 is sosecured to the shaft 135 that when its flat side 178 is under the block181 and the shaft 135 is not being positively rotated in eitherdirection the recess 115 is securely held in the plane described. Afterthe rotation of the twister-shaft in one direction to complete the eyeof the tie it dwells or remains non-rotary while the eye-forming pin 117and the bending-finger are withdrawn and immediately thereafter thetransferrer-arms begin to rotate another quarter-revolution to bringanother blank to the bending and twisting mechanism, while the rack 142moves in the return direction to reverse the shaft 135 to prepare it forreceiving the next blank. At the end of this return movement of the rackits roll 113 is in the other straight portion of the cam-groove 111 andthe shaft 135 is held in proper position by the block 181 bearing on thefiat side of the collar 177.

r1`he collar 177 is flattened for only a portion of its length, as shownin Fig. 12. lVhen the block 181 rests upon the flat side 178, it acts asa hook or stop to prevent forward motion of the shaft 135 while thesleeve 150 is being' moved forward to double the wire by means of thepin 1417 and the linger 155. As the twister-shaft 135 makes its firstrevolution the block 181 rides onto the untlattened portion, the shafthaving su fiicient longitudinal play to permit this, and the twisting ofthe wire loop draws the shaft 135, and hence the collar 177, forward, sothat by the end of one revolution and until the shaft is returned to itsiirst position after a bale-tie is finished the block 181 rides upon thefull round part of the collar 177 and allows free end movement of theshaft 135 as the twisting of the loop progresses. The forward movementof the shaft is limited by a yoke-piece 138', (see Figs. 1 and 2,)adjustably secured to the rear end of the cap 137 by the screw 183,passing through a slot 138 in said yokepieee, the said yoke-piecestraddling the shaft and serving as a stop against which the pinion 188,secured to the shaft, may abut. This contact of the pinion with the stopor yokepieee occurs just before the shaft 135 has iinished itsrevolution, thus enabling a tight twist to be given.

The finished tie is held in the openings or recesses of the arms 123 bythe hooks 125 until the ends oi' the levers 120 contact with the stopser lugs 132, (see Fig. 28,) it being understood that there is one ofsaid stops or lugs for each set of arms 123. This contact opens thehooks or latches which hold the finished tie and permits the latter todrop into a final receiver or rack composed of arms 1.8i-, which aresuitably connected with portions of the frame or standards.

The means for audibly indicating when a predetermined number of finishedties have been deposited in the rack are as follows: A star-wheel 185(see Figs. 28, 20, 30, and 31) is carried by a shaft 180, mounted in abearing 187, supported by or formed in one of the standards-in thisinstance standard 70. Each of the arms 23 of the adjacent set providedwith a projecting lug or pin 188, which is adapted to engage one of theteeth of the star-wheel and partially rotate it as each arm 123 passessaid star-wheel. rlhe other end of the shaft 186 carries a worm 180,meshing with a worm-wheel 100, mounted to rotate on a stud 101, which isattached to and supported by a suitable arm or bracket oi' the standard70, said arm being indicated in section in Fig. 30 at 102. The stud 101carries a fixed disk 103, from which a piu 101 projects, and mounted onthe stud is a sleeve 105, a bell 100 being mounted on the outer end ofthe stud. Projecting from the sleeve is an arm 107, having a pin 10syand a spring 100 is coiled about the sleeve and has its ends bearingagainst the pins 10-t and 108, with a tendency to keep the sleeve 105and arm 107 in the position shown in Fig. 31. Another arm 200 projectsfrom the sleeve and supports the spring-shank 201 of a bell-ham mer 202.Pivoted to the disk 103 at 203 is a lever 204, having its longer end 205provided with a tip or toe 200, adapted to bear on the lower side of thearm 200, and the other end 207 adapted to abut against the other side ofthe sleeve to limit the outward movement of the longer end 205 of thelever, it being understood that the tendency of spring 100 to hold theparts in the position shown in Fig. 3 causes the arm 200 to press thetoe 200 of the lever outward.

Projecting from the side of the worm-wheel 190 are pins 208, there beinglive of such pins iu the form of construction shown in Fig. 31, whichpins successively operate to cause the hammer to strike the bell in themanner presently described.

The operation of this portion of the meeh anism is as follows: Eachquarter-revolution of the transferrer discharges a. finished tic andalso partially rotates the star-wheel 185. This causes a slightrot-ation of the wormwheel, and one of the pins 208 moves a shortdistance along the cani-shaped outer surface of the longer arm 205 ofthe lever, and the IOO successive operations ol' the star-wheel finallyadvance said pin along the lever and gradually carry the arm 200 upwardand move the sleeve 105 against the tension of spring 100. When the pin20S that has been so operatin g alon the vlever reaches the shoulder 209thereof, the lever is released, since the edge of the lever, from theshoulder 200 to the tip 200, is concentric with the center of the pivot203 of said lever. The lever being thus released, the sleeve 195 and thearm i207 are thrown suddenly back by the spring 100 to the positionshown in Fig. 3l, and this sudden movement throws the striker 202against the bell, the position of which is indicated by the dottedcircle in Fig. 31.

rlhe operations of the different parts of the machine having beenmentioned in connection with the detailed description of the mechanisms,the operation of the machine as a whole, if not already apparent, willbe made clear by the following general description: The wire from whichthe ties are made is drawn from a coil or other source of supply (notshown) through the straightener 4S, if it is found necessary to so treatthe wire, and it then passes to the disks B0, which have an intermittentrotation in the direction of the arrows in Fig. 2, the extent of thisfeeding movement being adjusted according to the length desired for thecompleted ties. The wire is pushed by the disks through the guide 51 andthrough the passage-way in the temporary holder or receiver 71- 7 andthrough the openings in the arms 123 of the rotary transferrer. Then theproper length has been so fed, the disks cease to rotate and the cutter57 severs the wire at the rear end of the guide. rl`hen the temporaryholder opens and the shaft 07 of the transferrer makes one-fourth of arotation and brings other arms 123 into position to `receive a severedblank and the first one is moved to carry the just-severed end into therecess 145 of the twister-shaft 135. The pin 147 is next moved acrossthe recess 145, and the bending- Iingerl carries the short end of thewire around the pin 1.45, after which the jaw 171 clamps the doubledportions of the wire and the shaft 135 rotates to twist the doubledportions of wire between the pin 147 and the holding-jaws. rlhe loopedand twisted end ofthe wire is then released both by the holding-jaws andby the pin 147, and the shaft 97 of the transferrer makes anotherone-fourth of a rotation, so that the arms thereof bring the secondblank to the twister and carry the completed tie down to be dischargedinto rack 181 for holding a number of the completed ties. Eachintermittent movement of the transferrer partially operates the gearing,which iin ally causes the hammer 202 to strike the bell 190 and indicatethat the predetermined number of ties have been deposited in the rack.
